Heat pump vs. furnace: which is right for your home?

This is the most common question we get, and the honest answer is: it depends on three numbers — your electric rate, your gas (or oil) rate, and your winter design temperature. Here's how to think about it like an engineer instead of a salesperson.

Where heat pumps win outright

• You heat with oil, propane, or electric baseboard: switching to a heat pump is usually a dramatic, immediate win — often 30–50% off heating costs.
• You also need AC: one system replaces both the furnace and the air conditioner, and modern cold-climate units heat confidently well below 0°F.
• Your state pays for it: heat pump rebates are the largest in home energy — programs have covered thousands of dollars, specifically to get homes off fossil heat.

Where a high-efficiency furnace still makes sense

• Cheap natural gas + expensive electricity: in some markets, a 96%+ AFUE condensing furnace is the lowest-operating-cost heat.
• Your AC is newer but your furnace is dying: a furnace swap alone can be the right surgical fix.

The answer nobody markets: dual-fuel

For many homes in Illinois, Pennsylvania, and the colder Northeast, the winning design is both: a heat pump handles 80–90% of the season at the lowest cost per unit of heat, and a high-efficiency furnace takes over automatically only on the coldest stretches. You get the cheapest possible heat every single day, and both sides of the system are typically rebate-eligible.
